Be it known that I, HENRY M. Simian, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Radiators for Hovers or Brooders, of which the following is a specification.

My invention relates to an improvement in radiators for hovers Or brooders.

The object is to provide means for uniformly heating and quick circulation of the air, as well as perfect ventilation of the area being heated; and, incidentally, to

' guard the flame against undue and irregular drafts of air, and to afford safety and to create a healthy atmosphere for the chicks.

In the accompanying drawings Fig. 1 is a section showing the relation between the canopy and the radiator;

Fig. 2 is a section through a form of the radiator;

Fig. 3 is a top plan view; and

Figs. 41 and 5 show slight modifications.

In the construction shown in Figs. 1, 2 and 3, I propose to employ a fixed hollow body B, and in the most approved form this will taper, or have the shape of an inverted truncated cone as shown in Figs. 1, 2 and 4, although obviously it might be cylindrical as shown in Fig. 5. The hollow body B will also be firmly fastened to the oilwell or oilfeed pipe 1 of the burner A, whichever may be found most desirable.

The tapered shape of the hollow body B offers the following advantages, to wit: greater space for the air intake tubes C, permitting the use of larger tubes; greater heat radiating surface at the top where the largest amount of radiation is needed, and correspondingly less radiation at the bot= tom where less heat is required; and greater area for the outlet of the products of come bustion permitting the use of a narrower space when constructed as shown in Figs. 1, 2 and 4.

The tubes C project downwardly from a removable cover D. This cover is in the form of a disk, and when made as shown in Figs. 1 and 2'rests upon, and a little above, the upper edge of the chamber B to afford space between the two for the easy escape of the products of combustion, but when formed as shown in Fig. 4, with the small holes 2 at the top of the chamber B, the

plate or disk D" rests directly upon the top 'of hollow body B. Furthermore, when made in this tapering form, the hollow body provides space for large down-draft tubes or intake tubes 0, large enough in fact so that the upper ends can be covered with from #24 to #26 mesh gauze screen 3, and still admit abundant air for the burnerA. The gauze, however, is unnecessary, and the construction as illustrated even without the gauze screen is absolutely safe, unless gasoline is deliberately squirted or poured into the air intake tubes C.

In my improved construction, the outlet of the products of combustion is not retarded, the enlarged top of the tapering form of hollow body giving room for expansion of the products of combustion, so that the escape of the products of combustion is rather hastened than retarded; and this is particularly true of the heat travel to the edge of the canopy E, and the rapid warming of.

the air in brooder-house.

In Fig. 1, I have shown the relation of radiator and canopy. The cover D prevents the direct heat of the burner orradiator from striking the canopy as in general practice, and this will somewhat reduce the heat radiation of the canopy into the brooderhouse, but this loss of heat is more than offset by the increased volume of heated air that is forced out under the edge of the canopy due to the rapid travel of the prod nets of combustion, together with the increased radiation of cover D and hollow body B, the cover D acting as a deflector or baffle.

Thus a continual, rapid and uniform circulation of pure heated air is created in a very simple way, and by simple, mechanical instrumentalities. The device is so simple that it lends itself effectively to the purpose, does not easily get out of order, and provides means for easy and quick accessibility to the burner.

I claim:

1. A device of the character described in.- cluding a hollow body, a burner therein, and a cover having down-draft tubes terminating in the hollow body, said hollow body having means of escape of the heated air extending therearound and immediately below the cover.

2. A device of the character described including a hollow body, a burner therein, and a cover having down-draft tubes terminating in the hollow body, said hollow body having an annular outlet adjacent and immediately below the cover, the cover having its edges projecting outwardly over the edge of the hollow body forming a baflie-plate therearound.

In testimony whereof I afiix my signature HENRY M. SHEER.
